Got them out! Took about 2hrs. Don't know if there is a orderly way,but took the outside ones out first. I used two nylon faced hammers with rubber handles as levers,and used the middle liner as a fulcrum. A friend helped,and I think this helped,both either side,levering in turn,and some gentle tapping,and plenty of wd40 helps? The middle one was more of a challenge. But we decided to use two thin,angled metal brackets between the liner,and the block,and used two old wood chisels of all things as levers,rocking back and forth,and it did the trick!! This job proves how important regular coolant changes are,as there is hardly any corrosion on the liners,or bolts. Deciding now whether to get liners honed,and fit new rings??

Swansea Auto,a local auto machine shop,quoted £5 per liner to hone. Not done a full examination,but some xhatch does seem to have worn away?
My advice, if you can still see the cross hatch, leave it. I've never come across anyone with proper line boring machines that charge the service out at £15 an hour, stay well away
So is there an indication of what was holding them?
Just put it down to them being a 'snug' fit? And the fact that any effort exerted needs to be upward,which is not easy. Surprised Triumph didn't come up with a tool? Some good ideas on here if you do search You could use an engineers clamp on the middle liner using the 2 flat edges just to give them a twist to break the seal?I checked the 'top' ring in its relevant liner earlier,and ring gaps ranged from 0.4 - 0.43 top and bottom of the bore. Haynes state the gap spec 0.2 - 0.41. But also states the end gap is not critical unless it exceeds 1mm?
Worth a try ST? Their so 'snug',I'm sure I could've left them? But after trying to get them out,got my doubts now? Not sure how much movement breaks the seal? Also,Didn't expect the pistons to clean up so well in situ.
